Asymptotic Algebraic Realization of SU(3), Baryon Classification,gA (0), andDFRatio

In the framework of the chiral $\mathrm{SU}\mathrm{}\left(3\right)\mathrm{}\otimes \mathrm{SU}\mathrm{}\left(3\right)\mathrm{}$ charge algebra and asymptotic SU(3), a scheme of asymptotic algebraic realization of SU(3) is proposed. For the axial-vector couplings, it yields $\frac{D}{F}=\frac{3}{2}$ but $g_A\mathrm{}\left(0\right)=\frac{5}{2}\sqrt{f}$, $f$ being the universal fractional contribution ($\approx 50\%$) to the sum rules coming from the ground-state baryons. Neither the assumption of saturation by lowlying states nor the introduction of large configuration mixing is necessary.
